Hasnain Butt

I’m a Senior Data Engineer with 10+ years of hands-on experience designing and delivering scalable data platforms across Healthcare, SaaS, Fintech, and E-commerce. I’m strongest in SQL and programming languages like Python, Scala, Java, and PySpark, and I build robust ETL/ELT and distributed data processing solutions.

I’ve architected cloud-native platforms on AWS, Azure, and GCP, including data lakes, lakehouse patterns (Delta Lake, Iceberg), and enterprise data warehouses (e.g., Snowflake, Redshift). In my work, I focus on reliable pipelines, orchestration workflows, CI/CD automation, and performance/cost tuning that keeps production systems stable and efficient.

I bring a governance and quality-first mindset: I’ve implemented data governance frameworks covering metadata management, data lineage, data cataloging, and data stewardship. I also build data quality validation and automated monitoring, and I’ve ensured HIPAA-compliant processing of PHI/PII data and secure cloud data management practices.

I lead cross-functional delivery, mentor engineers, and help teams ship analytics-ready datasets that support reporting, predictive analytics, feature engineering, and AI/ML-driven pipelines. Most recently, I’ve delivered enterprise Lakehouse architectures and modernized warehouses and cloud migrations while partnering with business stakeholders, analysts, architects, and data scientists.
